Answer:
In any instance.
Step-by-step explanation:
A triangle has three sides, and the angle measures for all three angles will add up to a total of 180°.
∠A + ∠B + ∠C = 180°
<u><em>Example:</em></u>
Find ∠C if ∠A = 60° and ∠B = 50°.
60° + 50° +∠C = 180°
∠C = 70°

Answer:

Step-by-step explanation:

Answer:
the two angles are 55° each
Step-by-step explanation:
Let the two equal angles be y each
Therefore,
70° + y + y = 180°
Collect like terms
2y = 180 — 70
2y = 110
Divide both side by the coefficient of y i.e 2
y = 110/2
y = 55°
Therefore, the two angles are 55° each
